As one of the elements widely distributed in nature, manganese exists in the crust in the form of carbonate, oxide, silicate and other minerals. As an important industrial raw material, manganese and its compounds are more and more widely used in metallurgy, chemical industry, light industry, medicine, machinery, national defense, communications, agriculture and other industries in today’s social development. Therefore, how to choose manganese carbonate ore grinding mill equipment?
After years of development, the technology of producing electrolytic manganese metal with manganese carbonate ore in China has formed a relatively mature production process. First, manganese carbonate ore grinding mill equipment is used to grind manganese carbonate ore, and then liquid preparation, leaching, purification, electrolysis, passivation, washing, drying, stripping and packaging.
The process of manganese carbonate ore grinding mill includes wet grinding and dry grinding. Wet ball mill can be selected for wet grinding. Its advantages are: strong adaptability to materials, high output, suitable for large powder processing projects, good equipment stability, shortest process, no need for further pulping; The disadvantages are: large energy consumption, heavy equipment, large noise, difficult to accurately control the product size, difficult to accurately measure the material, making the subsequent continuous leaching process difficult to maintain stability; Moreover, the regulations of the industrial policy of electrolytic manganese metal on the unit consumption of new water limit the production of wet grinding. Dry grinding uses dry manganese carbonate ore grinding mill equipment, which has the following advantages: mature process, short process, simple configuration, and easy to control the subsequent continuous leaching process; The disadvantage is that the production process will produce dust pollution; In the case of high water content of materials, it is necessary to increase the hot air system to ensure normal production. At present, dry grinding process is generally used in the grinding process of electrolytic manganese metal industry.
In the manganese carbonate ore grinding mill equipment, the material is mainly subject to the rolling action of the grinding roller. At the same time, due to the speed difference between the grinding roller and the grinding plate, the material is sheared and ground; The materials fed into the center of the grinding plate move towards the periphery of the grinding plate under the action of the centrifugal force of the rotary table and enter the roller table between the grinding roller and the grinding plate. The grinding roller rolls the materials in the roller table under the action of the hydraulic device and the pressure mechanism. The rolled materials continue to move towards the edge of the grinding plate and overflow from the retaining ring at the edge of the grinding plate; At the same time, the hot air is sprayed upward from the annular nozzle around the grinding plate at high speed to suspend and dry the materials, so that the coarse particles can be blown back to the grinding plate for re-crushing, while the fine powder enters the upper powder concentrator with the hot air for separation, and finally the qualified fine powder with a certain particle diameter overflows from the upper part of the manganese carbonate ore vertical roller mill with the air flow into the dust collector for gas-powder separation, so as to obtain qualified ore powder; The coarse powder is returned to the grinding mill and ground again with the feed material. Materials with different humidity can be dried by adjusting the temperature and volume of hot air; The particle size of the grinding material can be adjusted by using the frequency control of the separator motor.
The HLM manganese carbonate ore vertical roller mill of HCMilling(Guilin Hongcheng) integrates crushing, drying, grinding, conveying and dust collection. It can be used as manganese carbonate ore grinding mill equipment, with the advantages of large output, high grinding efficiency and high classification accuracy.
